Details and patient eligibility

About

To assess the RELIABILITY in terms of accuracy of 3D-CT and 2D-CT reconstructions compared to intraoperative data regarding bronchovascular anatomy and tumor location. 3D CT reconstruction (CT scan without contrast injection) with Innersight3D® is equivalent to 2D CT (CT scan with contrast injection) for planning a minimally invasive lung segmentectomy.

Evaluate the impact of 3D reconstruction (from a CT scan without injection of contrast agent) on intraoperative and postoperative results
